I mean the ref was bad during the game but this was one time he made the right call. Buffon has no right to get in his face like that.
Did he? If a ref assigns a penalty every time there's a contact inside penalty box or the attacker gets disturbed by the defender, the game will turn into a penalty shoot-out competition. Bottom line is Benatia got to the ball before Vazquez fair and square, to me that's never a penalty. If you start assigning penalties when defender gets the ball and makes contact with striker afterwards, the strikers will learn how to get 10 penalties per game, this is not basketball where defenders are allowed to do almost nothing.
I don't care much about the red, at that point damage was already done, in a penalty shootout goalkeeper literally stands no chance if the striker strikes the ball well, doesn't matter if goalkeepers name is Woj or Gianluigi. It's just physically impossible to fly after a ball fast enough if the striker puts it in the top corner, only exception is if the ref allows you to jump off the line before the shot.
